Autonomerc mobility

WILL a cactus falling in the desert make a sound if there's no one to hear it? Does an autonomous car need a steering wheel if nobody is driving it?

The second may not actually be a philosophical question but Mercedes-Benz has an emphatic answer nonetheless.

According to the German luxury carmaker, the steering wheel, throttle and brake pedals will remain standard equipment because it "does not want to automate the fun out of driving".
